[Roentgen diagnosis of interstitial nephritis (pyelonephritis) by excretory urography and renovasography. Indications and diagnostic value of both methods including elektronic harmonization (author's transl)].
The roentgen signs of pyelonephritis may well be demonstrated by intravenous or infusion excretory urography. Discrete lesions of the calyces are better demonstrable by means of electronic magnification and harmonization. Inflammatory disease of the kidneys have characteristic patterns of vascular formation in renal arteriography. Electronic magnification and harmonization allow to detect initial stages of this illness.
